31. What is the initiator in the polymerization of isobutylene?
32. What is the general name of the product produced by cationic initiation?
33. What reactant besides the monomer is present in cationic chain propagation reactions?
Answer 31):-
The initiator used in the polymerisation of isobutylene are Lewis acids, such as BF3 , AlCl3 , SnCl4 , TiCl4 ....etc.
------------------------------------
Answer 32):-
Carbocation (cation) is the general name of the product produced by the cationic polymerisation...
-------------------------------------
Answer 33):-
Besides the monomer, the reactant used in cationic polymerisation is the carbocation or cation generated in initiation step (as, in the intiation step of the polymerisation of isobutylene) .....

Explaination:-
The whole mechanism of cationic polymerisation of isobutylene is given as:-
